ASTM A153 Stainless Steel Lag Bolts Hex Head Wood Screws Heagon Lag Screws
Products Description
These 316 stainless steel screws have excellent resistance to chemicals and salt water and are a good choice for ACQ-treated (arsenic-free) lumber. The flange reduces the risk of crushing material and the hex head provides a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Screws may be mildly magnetic. Head height includes the flange. Length is measured from under the head.
